Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani also said that Qatar, a key mediator in Gaza ceasefire talks, was 'reassessing everything' on their involvement in future talks.

Qatar's prime minister warned that an unprecedented Israeli strike in Doha targeting Hamas killed hope for Gaza hostages on Wednesday, September 10, calling for Israeli leader Benjamin Netanyahu to be "brought to justice." His comments came a day after deadly strikes targeted Hamas leaders in Qatar – a US ally – a first in the oil-rich Gulf that rattled a region long shielded from conflict.

The attack, just three months after Iran launched a retaliatory strike on a US airbase in Qatar, also cast serious doubt on Qatar-mediated Gaza ceasefire talks and undermined security reassurances to the Gulf from key ally Washington.

"I think that what Netanyahu has done yesterday, he just killed any hope for those hostages," Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani told CNN. Doha is "reassessing everything" around their involvement in future ceasefire talks and discussing next steps with Washington, he added in comments cited in CNN's live blog after an interview with the broadcaster.

Israel vows to 'act against its enemies everywhere'

Earlier Wednesday, Defense Minister Israel Katz vowed that Israel would "act against its enemies anywhere" while Netanyahu urged Qatar to expel Hamas officials or hold them to account, "because if you don't, we will."

Qatar has hosted Hamas's political bureau since 2012 with Washington's blessing, and has been a key mediator in Gaza talks alongside Egypt and the United States.

The White House said Trump did not agree with Israel's decision to take military action. Trump said he was not notified in advance and when he heard, asked his envoy Steve Witkoff to warn Qatar immediately – but the attack had already started.

Israel's ambassador to the United Nations, Danny Danon, sought to justify the decision, telling an Israeli radio station: "It was not an attack on Qatar; it was an attack on Hamas."

Palestinian militant group Hamas said six people were killed in Tuesday's strikes in Qatar, but its senior leaders had survived, affirming "the enemy's failure to assassinate our brothers in the negotiating delegation."

Hamas political bureau member Hossam Badran said Israel "represents a real danger to the security and stability of the region." "It is in an open war with everyone, not just with the Palestinian people," he said.
